ENGLISH ABSTRACT: The development corridor concept has been regarded as an important development instrument in spatial planning and geography for many decades. Expanding literature on the theme indicates that development centres or nodes play an important role in the establishment of such corridors. Flows of goods and information between such centres are key in creating conditions that are potentially favourable for further urban development along the communication axes connecting such centres. Combined, the various nodes form a unique flexible exchange environment allowing for dynamic synergies of interactive growth that can achieve scope economies aided by fast and reliable corridors of transport and communication infrastructure. In the South African development sphere, there is strong belief that functional relationships between nodes can play a decisive role in the establishment of development corridors. This research showed that the degree to which economic activities are concentrated in the greater Gauteng region; the resulting current or emerging multinodal structural composition; and the flows of economic activities between the various nodes result in the creation of developing corridors that channel and focus economic growth between networks of cities. This confirms the importance of corridors as spatial and economic development instruments. The research concluded that corridor development in Gauteng still favours monocentrism. Johannesburg and Pretoria feature as the most dominant nodes, exerting great forces of attraction on the distribution of development and economic growth in the region. The research also suggests a degree of polycentrism whereby economic growth is channelled between networks of cities, however development potential is most favourable in areas in close proximity to primary centres and tends to be functionality driven.
